Rocks And The Rock Cycle
Rock families are different kinds of rocks. There are 3 rock families: Igneous Rocks-form when hot magma or lava cools and solidifies. Magma is melted rock inside the earth. Sedimentary Rocks-make up about 75% of Earth's rocks. Made in layers, these rocks get made by the layers being pressed together.
Metamorphic Rocks-These rocks are rocks that were sedimentary or igneous rocks that have changed.Most, if not all metamorphic rocks form inside the earth.
